That error just means that an Image file your application (and / or gtk theme) is using isn’t compatible with your current SRGB profile, I wouldn’t worry about it unless the application won’t run at all…

Every time I start dvd styler or mkvinfo I see this error message. Very annoying…[/quote:rijx46dm]

I’m not sure what exactly causes this but I have seen it numerous times with more than a few programs. The only thing you can do is report the bug to the developers and wait for an update. It can be frustrating I know!
